There is no golden rule or value that fits all scenarios. Usually 32 is a good value to start with, however it might not be perfectly tailored for your environment. To give you an idea, currently you are issuing a checkpoint every 32*16MB of WAL traffic (or every 10 minutes). Maybe you can describe us better your workload, if it is subject to usage spikes or regularly distributed throughout the day mainly in terms of inserts/updates/deletes. I would gradually try and increase checkpoint_segments by 32 and monitor the effects.
